Professional bulk handling – Turnover up to 1000 t per hour
The powerful hydrostatic transmission and advanced Liebherr electronics ensure short, productive working cycles
during bulk handling.
• During grab operation, hoisting, slewing, and luffing are
driven simultaneously at maximized speed to achieve the
highest (possible) turnover.
• During grab filling, features such as automatic lowering and
hoisting guarantee the optimum filling level of the grab.
• The slack rope monitoring system ensures extended lifetime of the ropes and increases operational safety.
• Reverse power is returned to the drive process through
closed loop hydraulics which results in reduced fuel
consumption.
®
• The Cycoptronic
anti-sway system automatically
compensates for all rotational swing, transverse and
longitudinal sway of the load at maximum speeds.
• To provide safe and stress-free working conditions for
®
the operator, Liebherr offers the Cycoptronic
®
Teach-In
feature, a semi-automatic system, which pilots
including
the crane from the vessel hatch to the quay without
any sway. Especially for bulk operation into hoppers,
®
the Teach-In
system increases turnover and ensures
consistent turnover rates during the entire ship unloading.
• Liebherr technology is absolutely resistant to all types of
dust and dirt due to the closed hydraulic system and an
electronic system which is military proven and tested.
• The airflow needed for cooling hydraulic and engine
systems is routed external from the main machinery
house. This helps keep the engine room clean and free
of debris.

Professional container handling – Turnover up to 35 cycles per hour
Precision to perfection: With incredibly short acceleration times for all crane motions, Liebherr is the top performer in
container handling.
• The crane can be fitted with various types of spreaders
(fixed or telescopic) connected to the rotator. Manual, semi
or fully automatic telescopic spreaders are available for
various container sizes.
®
• Liebherr Cycoptronic
is an accurate, sway-free load motion
control system that uses in-house designed software.
®
Cycoptronic
allows for direct load positioning and aids
the crane driver in mastering his task. With Cycoptronic
turnover, safety and the confidence of the operator will be
improved.
• Safety: The luffing cylinder is positioned above the lattice
boom. This eliminates the possibility of any damage to the
cylinder through swinging loads or highly stowed rows of
containers on board the vessel.
• The Liebherr hydrostatic drive is the most reliable and
highest performing drive system for mobile harbour
cranes. Independent closed loop hydraulic systems utilize
®
the minimum number of components to guarantee highly
responsive, smooth and precise operation while maximizing
operational safety.

Practical solutions
Liebherr develops and produces special designs and solutions to meet
customer-specific requirements
• The Liebherr Portal Crane, LPS, is an efficient combination
of a space-saving portal (mounted on rails) and the proven
mobile harbour crane concept. Particularly on narrow quays,
individual portal solutions permit (railway) trains and (road)
trucks to travel below the portal.

• Liebherr Fixed Slewing Cranes (LFS) are an efficient
combination of a mobile harbour crane upper carriage and a
fixed pedestal. LFS cranes provide an economical and spacesaving solution for the installation on quaysides and jetties,
especially where room for manoeuvring is limited and low
ground pressure is essential.
